In an alternative embodiment, members 125 may be parallel tubes connected between frame member 102 (via joint 128b ) and frame member 103 without a third tube beam. In this embodiment, the extendable support member 125 and the extendable base frame member 101b are the primary mechanism by which the rear cargo area is used (see FIG. 8 ). In the unused position, the top of the extendable rod member 125 or a portion substantially near the top of the extendable rod member 125 is connected to the joint member 128b; the bottom of the member 125 or a portion substantially near the bottom of the member 125 in this way is connected to the frame member 103 in such a way as to allow it to slide vertically along the member 103 and to pivot about the same point. By sliding the u-shaped base vertically along member 103, member 125 can be moved from a closed, substantially vertical position to an open, substantially horizontal position. As member 125 is lifted along member 103, it is urged to a substantially horizontal position via joint member 128b (see Figure 10). This creates a new distance between member 102 and member 103, which simultaneously causes base member 101b to move parallel to member 101 to extend the base of the frame (see Figures 6 and 7), which simultaneously stretches member 101b, And thus use the rear cargo area. In alternative embodiments, there may be a spring, pulley, motor, or some other mechanism to assist the user of the cart 100 in extending the members 125 and 101b. In alternative embodiments, member 125 may have additional extension capabilities beyond pivoting upward, such as telescopically extending while also pivoting into an extended position, or extending via a hinge.

For example, the lock 130 provides a mechanism that includes the rear frame member 103 (tube), pivot, locking pin, shuttle, locking plate, spring, spring stop, locking actuator, and cable. The rear frame member 103 has slots cut to allow limited travel of the pin parallel to the handle and up and down the center plate of the rear frame member 103 . For example, the pivot is a metal pin that facilitates rotational movement of the rear frame member relative to the locking plate. The locking pin provides a locking lever for limiting rotation of the rear frame member relative to the locking plate. For example, the shuttle could be a plastic part that slides up and down inside the handle tube and couples the pin so the shuttle and pin slide up and down at the same time. The shuttle is continuously pushed up (down) by a spring that pushes the shuttle and pin back into the locked position. The shuttle has a cable attached thereto, with a lock actuator on or near the handle pulling the cable and thus moving the shuttle and pin into the unlocked state. The unlocked state is the state in which the pin is now inside the circular track of the locking plate and the rear frame member 103 can now be freely rotated to the non-use state (folded state). Locking plates may be mounted to the lower frame member 101B and may be located on each side of the rear frame member 103 . The locking plate may employ rail or step-slide translation and a locking receptacle for the pin to travel into. When the handle is rotated to an appropriate angle to align with the locking receptacle, the pin may be spring loaded to lock into the locking receptacle. The locking receptacle may be designed for a stowed (folded) state and an upright (unfolded) state.

Therefore, although a number of specific embodiments have been shown and described herein, it should be understood that any suitable arrangement which achieves the same purpose may be substituted for the specific embodiment shown. This disclosure is intended to cover any and all adaptations or variations of the various embodiments. Combinations of the above embodiments, and other embodiments not specifically described herein, will be apparent to those of skill in the art upon reviewing the above description.
所提供的本公开的摘要符合37C.F.R.§1.72(b)：其要求摘要将允许读者快速确定技术公开的本质。在提交时要理解的是，其将不能用于解释或限制权利要求的范围或含义。此外，在前面详尽的描述中，可以看到，出于使公开精简的目的，各个特征被分组到单个的实施方式中。公开的该方法不被解释为反映所要求的实施方式需要比每一权利要求中所明确记载的特征而更多的特征的意图。相反，如权利要求所反映的，本发明的主题在于：少于单个所公开的实施方式的所有特征。因此，以下的权利要求从而并入到详尽的说明中，每一权利要求立足于本身而表示独立的实施方式。The Abstract of the Disclosure is provided to comply with 37 C.F.R. §1.72(b): it requires that the Abstract will allow the reader to quickly ascertain the nature of the technical disclosure. It is filed with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the foregoing detailed description, it can be seen that various features are grouped into a single implementation for the purpose of streamlining the disclosure. This method of disclosure is not to be interpreted as reflecting an intention that the claimed embodiments require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter lies in less than all features of a single disclosed embodiment. Thus the following claims are hereby incorporated into the Detailed Description, with each claim standing on its own as a separate embodiment.
本说明书已经参考了数个示例性实施方式。然而，可以理解的是，所使用的词汇为说明性和示意性的词汇，而非限制性词汇。在不背离本公开在其所有方面中的范围和精神的前提下，如当前陈述和如所修改的，可以在所附权利要求的范围内进行多种修改。尽管说明书引用了具体的机构、材料和实施方式，但是该公开不旨在被限于所公开的具体细节，而是，该公开延伸到所有在功能上等同的、例如在所附权利要求的范围内的技术、结构、方法和用途。This specification has made reference to several exemplary embodiments.

Although the specification refers to specific structures, materials, and implementations, the disclosure is not intended to be limited to the specific details disclosed, but rather, the disclosure extends to all functional equivalents, such as within the scope of the appended claims. technology, structure, method and use.
